 The 4 — 20 mA or 0 — 10 V output signal is linear with temperature.The continuous analog signal path enables an extremely fast reaction time of the outputto a change in temperature (continuous analog measurement instead of digital samplingrate), resulting in a low-noise output signal that is insensitive to interference. A very highdegree of precision - even with small ranges - is ensured thanks to the range-specific gainadjustment. Digital communication allows the transmitter to be adapted to the measurement task(range, probe break and fine calibration).Two versions are available to suit specific requirements: Instruments with basic type extension 880/990 (adjustable)The transmitters are calibrated for a fixed range but can, at any time, be calibrated for adifferent range through the PC setup program. Instruments with basic type extension 881/991 (configurable)The required range can be configured through the PC setup program, without sensorsimulation and measurement.
